Contributor guide

Research direction
Examine the HTTP accept headers sent by version checker when fetching manifests from OCI compliant registries, and ensure that the 'Accept' header includes the correct media types for OCI manifests (e.g., 'application/vnd.oci.image.manifest.v1+json'). Check the registry client code for how it constructs requests and handle the response errors.
